Bearing assembly

摘要

A bearing assembly includes at least one outer ring and an inner ring unit including first and second inner rings, the inner ring unit having a central, axial bore extending through the first and second inner rings, and a plurality of attachment bores for attaching the bearing assembly to a bearing carrier. A first plurality of roller bodies is disposed between the at least one outer ring and the first inner ring and a second plurality of roller bodies is disposed between the at least one outer ring and the second inner ring. A pin extends through the central axial bore of the first inner ring and through the central axial bore of the second inner ring, and the pin maintains a predetermined preload on the bearing assembly by holding the first inner ring in a fixed position relative to the second inner ring.

1. A bearing assembly comprising:
at least one outer ring; an inner ring unit including a first inner ring and a second inner ring, the inner ring unit having a central, axial bore extending through the first inner ring and the second inner ring, and a plurality of attachment bores for attaching the bearing assembly to a bearing carrier, the plurality of attachment bores being spaced radially outward of the central axial bore and located away from an axis of symmetry of the bearing assembly; a first plurality of roller bodies rotatably disposed between the at least one outer ring and the first inner ring and a second plurality of roller bodies disposed between the at least one outer ring and the second inner ring; and a pin extending through the central axial bore of the first inner ring and through the central axial bore of the second inner ring, the pin maintaining a predetermined preload on the bearing assembly by holding the first inner ring in a fixed position relative to the second inner ring, the pin is press fit in the central axial bore of the first inner ring and in the central axial bore of the second inner ring, and a chamfer on a radially-inward edge of at least one of the first inner ring and the second inner ring, at least one groove on an outer surface of the first inner ring on a side of the first inner ring facing the second inner ring, the at least one groove extending radially outward from the chamfer and being configured to transport lubricant radially outwardly from the chamfer.
